Formerly the owner of a company that designed software for avionics (EFIS, FMS, etc.) and video games (Tetris, Robocop, Predator, Michael Jordan in Flight, and a number of others), I'm now retired and finally have the time to design, print, assemble, test and publish 3D models for my kids, grandkids and, hopefully, you and yours to enjoy.
